Washington Caps Carbon: Washington State adopted a carbon cap on large emitters, aiming to eliminate 167 million tons of CO2 equivalent through 2036. The cap, which will initially apply to businesses that emit more than 100,000 tons of carbon annually, could accrue $10 million in benefits. By 2035, the state estimates as many as 70 companies could be covered by the cap. (Politico Pro $, AP, San Juan Islander,NWPR)

Arctic Ice Shrinks to Summer Low: Arctic sea ice shrank to just 1.60 million square miles this week, hitting its summer low point and reaching a statistical tie with 2007 for the second lowest extent on record. This year’s minimum is approximately one million square miles less than the 1979 to 2000 average. National Snow and Ice Data Center Director Mark Serreze said he wouldn’t be surprised if the Arctic were “essentially ice free” by 2030.
